Oh thank you for correcting me, but hey.. I guess you can read.
666mhz is the ram frequency
450 is the CPU FSB frequency
You would need to push the 450mhz up to 666mhz for a 1:1 ratio.
Like this illistrates:
Intel Core 2 Duo E6850
2048 MB DDR3 Dual Channel
RAM Speed :700.6 MHz (1:1) @ 8-8-8-24
Freq : 4203.78 MHz (700.63 * 6)
This is my Last RESPONSE TO YOU. PHUCKEN MORON.

^Wow thats a nice speed there. I wounder how fast it is.
Anyways, the last post you made Grimmy made my head go boom.
BTW smile and try to be happy.
BTW look at this Q6600:
http://valid.x86-secret.com/show_oc.php?id=298228
Now thats a OC. I would love to see it in action.

^LMAO!!!!
Let me see if I can get this. DDR, or Double Data Rate, meaning it sends out 2 bits at a time means that at 333MHz it is effectively running at say 666MHz. Then you have it in dual channel mode that in turn causes it to run at 1333MHz (+/- 1-2MHz).
Therefore my Q6600 has a FSB of 333MHz quad pumped for effective FSB of 1333MHz and my memory is running at 333MHz effective 666MHz with dual channel giving it a true effective bus of 1333MHz therefore I get a 1:1 RAM to FSB ratio, correct?

Yes.
The thing to remember, the 1333mhz your referring to is the rated FSB of the CPU, since your saying quad pumped.
And by your CPU-Z, your using DDR2 800 below it's advertised speed, at DDR2 667. Since it double rated, you divide in half to see the actual speed its running. So in order to get a 1:1 ratio with your DDR2 800, you would need to push it to 400mhz (x9) for 3.6ghz OC.
So you can still get a 1:1 ratio even running it 533 (533/2=266x9=2.4ghz), for its stock speed, 2.4ghz by running it even slower. The same principle would be applied to DDR3. Its still double rated ram, hence 1333 / 2 is 667, you should be able to run it DDR2 800 or lower.

Fcukbag, I am asking about overvolting you stupid crack ho. I am asking why anantech had to overvolt the high speed ram they used on their overclocking benches at 400 and 450Mhz, which was the DDR3 PC3-14400, alot faster again that the 667 you keep yapping about. An answer like "the signal gets lost" or "out of tolerance" doesn't tell us anything, we know the signal is going to change like every other signal changes when you alter the amperage or voltage. Why does the PC3-14400 need to be overvolted? Try giving us some substance this time you vile maggot. This has been going on since page two and you still don't know, because you don't really understand RAM. Don't you feel stupid continually avoiding the same questions, yet posting irrelevant dribble at the same time?

So I was right. The main 1:1 people talk about is RAM to CPU meaning having the RAM equal to the CPU FSB. But in order to have your memory run at its rated speed and have the 1:1 ratio you would need to OC your CPU FSB insanely (withh DDR2 1066 +) to at least 533MHz (possible but insane).
One other thing thats making me ponder, if dual channel DDR causes your memory thats running at 666MHz to be effective 1333MHz then would Nehalems triple channel memory give you a rated memory FSB of 1998MHz? Say its like my Q6600 with the memory running at 333MHz with the DDR making it 666MHz and the tri channel tripling the speed to 1998MHz.
Man all this stuff is confusing....they need to simplify the memory.

Yes, you have the general understanding for FSB:RAM ratio correct.
Now as far as running triple-channel memory, I believe it still acts like dual channel. You just have an additional channel for more memory bandwidth.
DDR2 800 for example gives you 6.4GB/s single mode. In dual-channel mode, then it has 12.8GB/s. But from what I understand for us using FSB, there isn't much of a difference.
So in theory, if you use DDR3 1600 (12.80GB peek transfer rate) on triple-channel, it will give you 38.40 GB/s bandwidth.
The main thing is, Nehalem doesn't have FSB, but Quick Path? Which is allot like AMD's HTT. So understanding memory wise is going to be different, especially when you look at stats on CPU-Z. You can't treat it like FSB like we are with our C2D or Q2D, which is prolly confusing you.. and me. :lol:

^Damn them and thier having to change things and such.
But still being able to not only utiilize the memorys bandwidth potential but giving more than current sounds grat.

Hi guys,
I am also looking into 1:1 ram ratio for a e8500 but is anyone finding difficult to find some decent 8GB(2gig sticks) 667 ram. All i could find is value select.
By the way Grimmy your posts are spot on in regards to ram ratio. I will passing this info to other people. Keep it up!
